I'd say there are 76 ways, right about now. Just wrapped up my latest co-op order, which was for 76 skeins. I capped it at 50 variegated skeins, plus an unlimited number of solid coordinating skeins. Usually there are maybe 10 trim skeins. This time, there were 26.
I could absolutely not have done this without my electric skein winder. It was well worth the investment--solidly made, flawlessly functional.
